The 49ers' 38 -13 domination of the Arizona Cardinals on Sunday is reflected in their PFF grades, which also offer insights on rookie quarterback Brock Purdy’s abilities.
Purdy completed 15 of his 20 attempts for 178 yards and three touchdowns, giving him a 141.2 passer rating -- his highest of the season. While Purdy’s average yards per attempt was 8.9, his average depth of target was his lowest since Week 14 at 6.4 yards.
The 23-year-old did get the entire offense involved, completing passes to six different targets. The run game also had several players contribute, with the Elijah Mitchell's return to the mix supplementing Christian McCaffrey. Rookie ball carriers J.P. Mason and Ty Davis-Price also made appearances in the win at Levi's Stadium.

On the defensive side of the ball, Nick Bosa fell one sack short of tying Aldon Smith’s single-season franchise record of 19.5, but the NFL Defensive Player of the Year front-runner's lone sack of the day gave him the league lead with 18.5 on the season.
The 49ers' defense limited the Cardinals' ground game to a measly 61 total yards and pitched a shutout in the second half.
Outside of the 77-yard trick play for a touchdown on the game's opening drive, Arizona QB David Blough and the Cardinals were limited to only 178 yards of total offense. Defensive coordinator DeMeco Ryans’ unit also forced three takeaways.
Here are more highlights from the 49ers' PFF grades:
San Francisco 49ers
Offense:
TE George Kittle - 89.9
The tight end caught four of his six targets for 29 yards and two touchdowns. The All-Pro tight end has racked up seven touchdown catches over the last four games, and his four straight games with a score is the longest streak of his career.
RB Elijah Mitchell - 89.1
The sophomore running back was only on the field for 10 snaps, but he carried the ball five times for 55 yards and two touchdowns in his first return to action since Week 12. Four of Mitchell’s five rushes resulted in either a first down or touchdown.
WR Brandon Aiyuk - 76.9
The third-year wideout caught four of his five targets for 59 yards, netting the first 1,000-yard receiving season of his NFL career. Three of Aiyuk’s four catches resulted in a first down.
RB Christian McCaffrey - 76.3
The All-Pro registered 10 carries for 45 yards and caught all three of his targets for 34 yards and a receiving touchdown. Two of McCaffrey’s three catches resulted in either a first down or touchdown. The Stanford product was only on the field for 30 plays, or 48 percent of the club’s offensive plays.
QB Brock Purdy - 76.1
The rookie’s sweet spot seems to be intermediate throws 10 to 19 yards downfield, where he completed all five of his attempts for 72 yards. Purdy only attempted one pass of 20 yards or more Sunday, which fell incomplete.
Purdy was under pressure on 10 of his 27 dropbacks (37 percent), completing three of his five attempts for 30 yards, one touchdown and 116.7 passer rating. The Cardinals did get to Purdy for four sacks and one scramble when under pressure.
When blitzed, Purdy's response might have been even better. The rookie was blitzed on 12 of his 27 dropbacks (44.4 percent) and completed eight of his 10 attempts for 87 yards, two touchdowns and a 142.5 passer rating.
